World’s smallest fuel cell presents

Researchers at the University of Illinois (USA) has succeeded in a fuel cell to shrink to microscopic dimensions: This tiny device has the dimensions of three by three millimeters and a thickness of one millimeter – and thus is the world’s smallest fuel cell functioning.

The hydrogen-powered unit will be portable devices or micro-robots with electricity. Total produce the first prototypes of the miniature fuel cell 0.7 volts voltage and 0.1 milliamps current. With a full tank, the system is 30 hours.smallest fuel cell

Currently, it is even easier, these batteries on size. In fuel cells is the major challenge of the necessary liquid pump and the electronics to miniaturize. “Such smaller components often require more energy for their operation, when the fuel cell system can provide,” explained the scientist Saeed Moghaddam. Its development requires no pump and therefore consumes no energy. The miniature fuel cell consists of only four components. A thin membrane separates the water from the area filled with metal. Among them, the electrodes are attached.

Surface tension rather than pump

Small holes in the membrane ensure that the water in the adjacent chamber as steam arrives. The steam reacts with the metal hybrid to hydrogen, which is a pressure rise of the membrane seals. The electrodes will eventually produce electricity and as soon as the pressure decreases, water is flowing further to see the reaction to maintain. This process requires no pump, it works only by the surface tension of water.

For the operation of a mobile phone is the produced energy to be low, however, the scientists reported that they adapted to design a current of 1.0 milliamps can achieve. This could still smaller electronic devices, such as micro-robots are operated

Fuel cells will start production in summer

The car manufacturer Daimler will already this summer with the first models with production fuel cell and start the production in the coming years to expand to 100,000.

“From the middle of the year we will be a moderate quantity production companies. We believe that an attractive product with no compromises can be,” announced CEO Dieter Zetsche in an interview with auto motor und sport. “And we are confident that we are in a period four to five years with an assumption of 100,000 cars a year, the cost of the fuel cell in the magnitude of the drive-a Bluetec Hybrids can bring. That was a short time could not be foreseen.”
Hydrogen filling station network push

Therefore, Daimler also calls for the development of a hydrogen filling station network forced. “We worked with a partner in Germany, a network of 1,000 gas stations are analyzed. In other words: Not more than 35 kilometers a customer must go until he reached the nearest gas station. This is not comparable to the gasoline supply, but sufficient.” According to Zetsche, Daimler for this analysis with lime worked. The investment required to set Zetsche Chains to the high cost to be able to afford. “The investments, which in Germany would have to be made, subject to 1.7 billion euros. No hurdle, which is insurmountable, but they can not from one alone. I’m thrilled with how far along this path we already have. “

Each year, a hybrid model

With the launch of the hybrid version of the S-class in this summer Daimler also wants each year, a new hybrid model on the market. “Our hybrid schedule begins in the summer with the S 400 hybrid. At the end of the year, depending on availability of the battery, it goes with the M-Class continues,” said Zetsche. “We are in principle, all the main series for the hybrid operation to prepare. That means that we will continue at least one new hybrid per year will imagine.” Zetsche also wants to reinforce the development of pure electric models. To be smart at the end of the year another 1,000 e-Smart extradite. “In addition, we are on the A-and B-class platform is a fully electric vehicle to prepare the 2010 initially in limited quantities will be. Around for 2011/2012, we see it as more realistic, with Smart and Mercedes with relevant, five volumes to come.

Zetsche: “We need reliable standards of the governments’

In order to develop emission-free cars, Daimler CEO Dieter Zetsche on Thursday (28.1.) On the World Mobility Forum in Motor Presse Stuttgart uniform and long-term arrangements required. The investments are so high and the building of infrastructure so burdensome that reliable standards are indispensable. The policy was required. “The transformation to a post-fossil mobility needs reliable standards. Customers expect predictability,” said Zetsche. “The beginning of the end of the oil era is here. We must massively in research and development investments, while almost all the markets fall.” So there is a “natural selection” in the auto industry. But the crisis was a chance that the German industry with better solutions at the end would be better off.

But it was wrong, now alone on the electric drive must be set. “We must also take the diesel and petrol engines, which come on the road, more efficient.” Before the internal combustion engine with electric drive is replaced, should the petrol and diesel initially by electrical components. The fact that the auto industry must change, including errors in the past has acknowledged Zetsche On. “I think I can for all my colleagues when I say: We must not for hunting bear. We have understood.”

Federal Economics Ministry is investing in energy efficiency and climate protection

The Federal Ministry of Economics and Technology has established its policy to promote research and development of advanced energy technologies in a program “Climate protection and energy efficiency” bundling. To the program sought modernization of Germany’s energy supply to drive forward innovation and the processes, the German Economics Ministry, the technology program funded by an additional Euro 15 million, so that for 2009 total Euro 115 million for the promotion of modern energy technologies to be available.

This German Economics Minister Michael Glos: “The financial gain of the technology program is an important step to promote innovation and modern energy technologies, because the only way to Germany, the energy challenges of the future master.”
For information and to develop ideas for a continuation of the research, the Ministry of Economy successful examples of the program in a brochure entitled “Climate protection and energy efficiency” zusammengestellt. The examples show the progress in various fields, such as in the field of modern power plant technologies, fuel cells and hydrogen, with the efficient use of electricity and storage technologies as well as the building and improved energy efficiency in the industry. The brochure can be ordered and is also available for download (see “Further information”).

Starting shot for the “Blue Tower Herten”

Economy Minister Christa Thoben presented today in the presence of leaders of the city and the investor Herten the Zuwendungsbescheid for the demonstration project “Blue Tower” to the CEO Dr. Heinz-J├╝rgen M├╝hlen H2 Herten Ltd. The “Blue Tower” is an important building block for the hydrogen competence Center of the City Herten on the grounds of the former colliery “Ewald.” The State of North Rhine-Westphalia promotes the project in the coming years with a total of 7.1 million euros.
Blue Tower Herten
“With the realization of the” Blue Tower “is an innovative process technology, which once again the leader of North Rhine-Westphalia in the hydrogen and fuel cell technology underpinned. Such efficiency technologies demonstrate the competitiveness of our businesses and make a significant contribution to climate protection, “said Economy Minister Christa Thoben today 21.01.2009 in Herten. The company intends H2Herten Ltd., the investment in 2009 is still in operation.

With the “Blue Tower Herten” is the first time a 13-megawatt prototype plant for the production and use of hydrogen energy from biomass will be achieved. The underlying asset of this procedure is the technician, Dr. Heinz-J├╝rgen M├╝hlen been invented and developed. With the “Blue Tower” will be the first time advanced process technology on an industrial scale demonstrated that this product gas derived from biomass (green waste) can be used directly for the operation of gas engines or for the production of hydrogen used. The “Blue Tower” includes a whole series of previous research projects, some of which are also protected by the country have been promoted.

Solar Millennium AG, Erlangen, is contributing more than 13 million euros in the realization of the current project in Herten. She wants the product gas obtained in the framework of a hybrid drive in solar power, and thus the basic needs “around the clock”, thus also to the times of the day on which solar energy is not available, cover.

Electrical industry relies on hydrogen

HB BERLIN. Sun to acquire environmentally friendly vehicles a greater range, with the batteries alone will not allow it. Was necessary but, with government promotion of a network of hydrogen filling stations to build.


For the introduction of electric cars in the next few years offer the hybrid technology, with a conventional internal combustion engine combined with a battery. Charged the battery can be referring to normal outlets. Such pilot projects, the German carmaker, in cooperation with major energy companies already started. The federal government has spent the goal that soon in the next decade, the first electric car to buy to be. By 2020, about one million vehicles enter.
